Elutrap® Electroelution System, GE Healthcare


The Elutrap™ system is designed to isolate nucleic acids and proteins from agarose or polyacrylamide gel slices by electroelution. Samples are purified with excellent recovery into volumes as low as 200 μl, without requiring sample pretreatment or special buffers.

  • Versatile system can be used for nucleic acids and proteins
  • Purifies nucleic acids 14 bp to 150 Kb; proteins larger than 3 - 5 kD
  • No salt cushions or special buffers required for elution
  • Adjustable trap allows optimisation of final sample volume
  • Electrophoresis chamber holds up to four Elutrap™ devices simultaneously

The Elutrap™ system can be used with most horizontal gel electrophoresis chambers. The Elutrap™ electrophoresis chamber allows the most efficient flow of current through the device and can be used for up to four samples simultaneously.

Assembly of the Elutrap™ system is very easy. Gel slices are placed in the middle of the Elutrap™ device, which is then placed into a horizontal electrophoresis chamber. Molecules migrate from the gel slice into a trap area formed by BT1 and BT2 membranes. The membrane placement is adjustable, allowing final elution trap volumes to be optimised for the particular assay. The Elutrap™ system can also be used for concentration of dilute solutions.

Ordering information: Elutrap® Starter Kit includes one Elutrap® device, 50 BT1 membranes, and 50 BT2 membranes. Elutrap® Starter Kit with electrophoresis chamber includes one Elutrap® device, one electrophoresis chamber, 50 BT1 membranes, and 50 BT2 membranes. Elutrap® Four-Pack includes four Elutrap® devices, 50 BT1 membranes, 50 BT2 membranes, and one electrophoresis chamber.
